Durability and surface finish
The bolts are based on ASTM 4140 or SCM 440 grade steel, which undergoes a heat treatment process. This procedure ensures consistent hardness and strength throughout the entire cross-section of the material. Corrosion protection is provided by a surface finish created by zinc plating or triple nickel plating followed by chrome plating. In addition, each production batch undergoes a salt spray test and a tensile strength test, confirming their reliability in demanding conditions.
